I agree with everyone who feels a * new * engine needs an oil change
after a few hundred miles, to flush out grit from machining / break in
I use synthetic, either way, oil / filter changes are a good idea
Climate is a factor, the Texans never see the intense cold us
Yankees love so much, when cold, the engine has more clearance, and runs
on a very rich mixture until warm, these two factors dirty up oil fast.
